A method and apparatus are provided for calculating the air charge mass for an engine as a function of four measured parameters. These parameters include the engine speed measured by a tachometer, a throttle position measured by a throttle position sensor, manifold air temperature, and barometric pressure. Without the need for a mass air flow sensor or a manifold absolute pressure sensor, the present invention provides a system for quickly and accurately calculating the air charge mass for the engine.
